Toa/ZZ whom t may concern:

Be it known that I, RODMAN W'. HATHA- WAY, a citizen of the UnitedStates, residing at Carbon, in the county of Adams, State of Iowa, haveinvented certain new and useful Improvements in Mowers; and I do herebydeclare the following to be a full, clear, and exact description ci theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

lhis invention relates to mowers, and more particularly to the cuttingmechanism thereof, the object of the invention being to provide aconstruction wherein the knives will move continuously instead of havingthe usual reciprocating motion.

A further object of the invention is to provide a construction andarrangement which will provide for an upper and a lower series ofknives, which will cooperate in the cutting operation, other objects andadvantages or' the invention having reference to details, which will beunderstood in the following description.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a top plan view showing a portion of a mower including oneform of cutting mechanism. Fig. 2 is a longitudinal vertical sectionthrough the knife band, including the carrying and guiding lrolls. Fig.3 is a vertical section at right angles to Fig. 2. Fig. 4 is a viewsimilar to Fig. 2, embodying a knife-band comprising links. Fig. 5 is adetail perspective view showing'a portion of a linked knife-band.

Referring now to the drawings, there is shown a portion of amowing-machine comprising a bar 10, which corresponds to the ordinaryfinger-bar and at the inner and out ends of which are the shoes 11 and12, which run upon the ground. Upon the shoe 12 in advance of the barl() are ears 13 and 14, which arespaced from each other and betweenwhich are disposed rollers 15 and 16, that are mounted upon shafts 17and 18, secured in the ears. The lowermost point of theperiphery of theroller or drum 15 is slightly lower than the corresponding portion ofthe rolle-r or drum 16 for a purpose to be presently explained. Upon theshoe 11 and spaced forwardly and rearwardly thereof are lthe ears 19, inwhich are mounted shafts 20 and 21, on which are formed the rollers ordrums 22 and 23, the lowermost point of the periphery of the drum 22being slightly lower` than the corresponding portion or the drum 23.

1n connection with thev structure above described there is employed aknife-belt 25, which is endless vand which passes around the drums 22and 15 and under the drums 23 and 16, the drums 23l and lserving to holdthe upper portion of the intermediate part of the belt 1n close relatlonto the lower portion thereof. At the front edge ofthe belt 25 are formedteeth 26, each having a cutting edge 27, lying at right angles to thedirection ol' travel of the belt upon the rollers or drums 22 and 15,this cutting edge being the front of the tooth. The back or' the toothis cut away to forni the incline 27, that leads to the.

base of the front edge of the next tooth in the rear.

If the roller or drum 22 be rotated, the teeth of the upper and lowerportions of the belt will travel 1n opposite directions and the cuttingedges of the upper and lower teeth.

will engage between them the stalks to be cut and will cut them.

'Ihe shaft 20 of the drum 22 extends beyond the ear 19 and is connectedwith the tumbling-rod 28, that is operated from the ground-wheel of themower. The rear edge of the knife-band is provided with notches 29,which are engaged by the teeth 30, formed upon the periphery of the rearend of the drum 22,' so that as the drum is rotated the knife-band ismoved to ef'ect the cutting operation. In Figs. 4 and 5 of the drawingsthere is shown a construction wherein the knives are in the forms ofpivotally-conne'ct.

ed links instead of being parts of a single band. There is a series oflinks 35 and a series oflinks 36, the links of one series alterhatingwith the other. The body of each of the links 35 is somewhat broaderthan the tooth 37, formed thereon, and adjacent to the side edges ofthis body portion are formed the slots 38 and 39, which extendlongitudinally of said body .portion and in which are engaged the hookedears 4() and 41respec-l tively, formed at the sides of the body portionof the link 36, from which projects the tooth 42. These links 35 and 36,which connected to form an endless band, are mounted upon the drums 22and 15', corresponding to the drums 22 and 15, and pass beneath the A ofeach ot' the teeth 37 and 42 are beveled, and

these beveled edges are sharpened and forni the cutting edges of theteeth.

lfinwa-rdly toward each other and engaged 'lhrongh'the t body portieriol each link 1s formed a perforetion 43, which is arranged lor,enga-genient by a tooth 44 of the drum 22', so that by rotation of thelatter the bend will be moved to cause the teeth of' the upper and otherseries being,l curved downwardly and through the said slots.

2. A knife-bend for mowers (-oxnprisine`- altr-mnuinf;l series ol`links; the links of one serios being slotted adjacent their lor itndlneledges, :ind the links ol' the orlnrsr-ries b1`-- lower links to move inopposition and eut the stalks against which the mower 1s moved.

Wlhat is claimed is 1. A knife-band for mowers comprising alternatingseries of links7 the links of each series having blades and having theirbody ortions of greater Width than the blades to orrn projectingportions, the extended portions of the links of one series beine'slotted and the extended portions of the links of the inga provided withoverturned flanges lor engagement in the slots in the links of the.other series, the links` of ene-h series being' provided with blztdes.
